1 Natica (Amauropsis) suturalis has so strongly the aspect of Natica islandica that I can easily believe connecting 

 links will yet establish their identity. The age of Natica islandica and its distribution, as well as its present habitat 

 in Subarctic and Arctic seas, make its presence in Antarctic regions more probable. But for the present it is impossible 

 to unite them.— (Watson, Zool. Chalk Exp., part 42, p. 456.) 



2 On comparing this [Natica (Lunatia) gronlanclica from Heard Island] with Sars' specimens from Norway I am 

 not quite satisfied, and yet I cannot part them. ... It was unsatisfactory to put a Kerguelen shell to an Arctic species 

 without fuller conviction, and I was glad, therefore, to have my determination of the species confirmed by Mr E. A. 

 Smith.— (Watson, Zool. Chall. Exp., part 42, p. 448.) 



3 I give this species [Odostomia rissoides from Marion Island] on the authority of Dr Gwyn Jeffreys. I had 

 remarked the shell's great resemblance in form to Odostomia rissoides, but the distinct and strong spiral structure which 

 characterises it, coupled with the locality, prevented my referring it to that species.— (Watson, Zool. Chall. Exp., part 

 42, p. 481.)
